How to fix?

Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.65.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: fix a use-after-free in r535_gsp_rpc_push()

The RPC container is released after being passed to r535_gsp_rpc_send().

When sending the initial fragment of a large RPC and passing the caller's RPC container, the container will be freed prematurely. Subsequent attempts to send remaining fragments will therefore result in a use-after-free.

Allocate a temporary RPC container for holding the initial fragment of a large RPC when sending. Free the caller's container when all fragments are successfully sent.
